EDWARD R. VIVES, OF NEW YORK, N. Y., ASS IGNOR TO VESDAL CE-EATIQNS, INU, NEW YORK, N. Y., A CORPORATION OF NEVT YORK.

KEY.

Application filed March 17, 1923.

To all whom it may concern:

Be it known that EDWARD R. Vrvns, subject of the King of Spain, residing at New York, in the county of New York and State of New York, has invented certain new and useful Improvements in Keys, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to locks of the multiple key type, and more particularly to keys adapted for use with locks of this type.

In my copending application filed of even date herewith, I have shown a combination lock in which the bolt controlling mechanism consists of a plurality of sets of disks and annuli, each set comprising a'plurality of disks and one annuli and the several sets being mounted to move bodily in parallel paths transverse, or at right angles, to the bolt; and in which the bolt has a number of pins corresponding to the number of sets of disks and annuli and adapted to intersect the paths of said sets, so that unless the several sets have been operated by a key so as to bring an annulus in alignment with each pin, the bolt cannot be retracted. In this look the combination is changed by chang inc the normal position of one or more annu i. The number of possible combinations is very great and indeed, for all practical purposes, unlimited. However, whenever a new combination has been set up in the lock a new key must be provided, and as the lock is designed particularly for use in large hotels where it is highly desirable to change the combination frequently, provisions should be made for forming keys quickly and easily and without substantial expense.

Therefore the present invention has for its object to provide a key form or blank of simple and cheap construction, from which a key can be readily formed to suit any combination which has been set up in a lock of the character described- Referring to the accompanying draw- 1ngs:

Fig. 1 shows a key blank embodying the invention.

Fig. 2 shows a modified form of the invention.

Fig. 1 shows a key blank consisting of a hand piece 1 and integral pins2. For use in the particular lock described in my co Serial No. 625,818.

pending application, the blank will have pins corresponding to the five sets of disks and annuli. Each pin consists of a number of equal sections formed by partly cutting through said pins at equally spaced points thereon, each section corresponding in length to the diameter of a disk or annulus and the length of the pins being such as to eifect a maximum movement of a set. IVhen it is desired to form a key from this blank to suit a given combination, it is only necessary to break off the required section or sections, which can be done readily and without the use of tools. A blank of this construction can be stamped out from sheet brass or other suitable material at an insignificant cost.

The key form shown in Fig. 2 consists of a body or hand piece 4.- having attached thereto five pins. As in the first form, each pin consists of a plurality of equal sections. each section exactly corresponding in length to the diameter of a disk or annulus. But in the present form the sections are frictionally connected, as clearly shown by the drawing. This form can very conveniently be converted into a key to suit any combination, as will be obvious from the foregoing description.

Now having described two specific embodiments of my invention, without intending to limit the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A key form consisting of a body having a plurality of pins projecting therefrom, said pins each including a plurality of detachable sections.

2. A key form consisting of a body having a plurality of pins projecting therefrom, each pin consisting of a plurality of equal sections detachable from each other.

3. A key form consisting of a body having a plurality of pins projecting therefrom, said pins being of equal length and each consisting of equal sections detachable from each other. i

4. A key blank, consisting of a body having a plurality of pins of the same length projecting therefrom, each pin being cut partly through at uniform distances along the length thereof, whereby said blank is adaptedto form a key corresponding to any combination by breaking off the required pin sections.

5 joined together by said reduced portions.

6. An integral key blank consisting of a body having a plurality of pins projecting therefrom, each pin consisting of sections joined together by reduced portions.

10 7 A key blank consisting of a body having a plurality of elongated pins project ing therefrom in the same plane, said pins being constructed to have portions thereof removed for the purpose described.

8. A key blank consisting of a body having a plurality of elongated pins formed integrally therewith and projecting therefrom in the same plane, said pins being of the same length and constructed to have portions thereof removed for the purpose described.

In testimony whereof I hereunto aflix my signature.
